CO2 Rebreathing Comparison
Based on scientific testing developed and conducted under the supervision of Dr. William W. Fox, Division of Neonatology, Children’s Hospital of Philadelphia, and Dr. Thomas H. Shaffer, Department of Biomedical Research, Alfred I. duPont Hospital for Children, the SafeSleep Crib Mattress poses a significantly lower hazard for carbon dioxide rebreathing than the tested firm crib mattress with a tight-fitting cotton sheet.
While the firm crib mattress represents a known low hazard item and is recommended by the American Academy of Pediatrics (AAP) to reduce sleep related risks, the SafeSleep Crib Mattress demonstrates a significant decrease in carbon dioxide retention compared to the firm crib mattress and presents a significantly lower hazard level than the firm crib mattress currently recommended by the AAP.
Results: The SafeSleep Crib Mattress has a 10 fold decrease in carbon dioxide accumulation compared to a firm crib mattress. It takes 2 minutes for carbon dioxide to dissipate on a firm crib mattress with a tight sheet; it takes less than 1/2 a second for it to dissipate on the SafeSleep Crib Mattress. An infant takes a breath every 1-2 seconds, meaning the carbon dioxide (poisonous gasses) would be gone before the infant takes their next breath of air – even if face straight down.
